A passenger yelled "Allahu Akbar...you're all going to die" aboard a Southwest Airlines flight on Tuesday.

Ali Reza Shahsavari, 29, was arrested after the flight made an emergency landing at the Rick Husband Amarillo International Airport in Texas at 3:30 p.m. on Tuesday. The flight from Los Angeles was scheduled to land in Kansas City, according to an Amarillo Globe News report.

The incident started with Shahsavari arguing with another passenger. The flight crew separated the men, according to the police.

Shahsavari then went into the bathroom and started yelling from the rear of the plane.

Passengers said he stood at back of the plane and yelled "You're all going to die, you're all going to hell. Allahu Akbar," which translates to "God is great" in Arabic.

“All of us guys were looking at him like, are we going to have to do something?” Passenger Doug Oerding, Sacramento, said while waiting to reboard the plane.
